Answer 1

9- 3

11- If a line is drawn parallel to one side of a triangle intersecting the other two sides in distinct points, then the other two sides are divided in the same ratio.

12- an = 3 - 4n

when n = 3,

a3 = 3 - 4 × 3 = 3 - 12 = -9.

13- 3 tanΦ = √3

3 tanΦ = tan60

3Φ = 60

Φ = 60/3 = 20.

18- AP- 5,8,11...

a = 5; d = 8-5 = 3

S10 = 10/2 ( 2×5 + (10- 1)3)

= 5(10 + 27)

= 5 × 37 =185 ans.

Thanks..
